Successful installation of /e/ Android Q on Sony Xperia XZ2 Compact (xz2c)

I also managed to compile and install Android Q (0.14) on my single sim xz2c (8134). I had LOS microg before and the explained installation guide didn’t work for me (maybe I took the wrong boot.img.), got Error: “kDownloadMetadataSignatureMismatch” So I tried with LOS Recovery and sinced my device didn’t boot later anything other than fastboot I downloaded newest (2021-03-12) and everything worked immediatly with it.

I ran into some issues, Calls work (but app crashes, again and again) so I need to reboot device to hang up. Installed a diffrent app and with it it worked. Bluetooth, WLAN, GPS and NFC works. Installing covid app I was greeted with missing API. So I tried to install from APPS. When I click install the APPS app crashes also.

Has anyone suggestions?

Oh and whats the difference of branch and tag? I went alog with the tag since I read often about in the community.
